Features

• Test Data Factories - Implements a comprehensive system for defining reusable data blueprints and factories to generate consistent test environments.
• Test Data Blueprinting - Provides a system for creating reusable templates with default attributes and nested inheritance to reduce repetition.
• Variant Definitions - Allows defining multiple factories for a single class and using inheritance to share common attributes across different roles.
• Test Attribute Grouping - Bundles shared attributes into reusable traits to mix them into objects during instantiation.
• Automated Association Generation - Automatically resolves and creates linked test objects based on class associations.
• Automatic Association Linking - Links factories together to automatically create related objects through implicit naming and polymorphic relationships.
• Test Object Associations - Automatically links related Ruby objects through implicit naming and polymorphic relationships during test data generation.
• Persistence Strategies - Provides flexible strategies to control whether objects are persisted to a database, built in memory, or stubbed.
• Blueprint Inheritance - Enables factories to inherit attributes from parent definitions to create specialized object variants.
• Test Data Generators - Creates complex objects and their associations for testing to replace the need for static fixture files.
• Attribute Traits - Bundles shared attributes into reusable traits that can be dynamically added to objects during instantiation.
• Dynamic Object Instantiation - Provides a system for creating complex test objects from reusable blueprint definitions and hierarchical configurations.
• Automated Test Data Generation - Creates flexible and reusable object blueprints to replace static fixture files in a testing environment.
• Database Object Mocking - Produces persisted or in-memory Ruby objects with complex associations for use in automated test suites.
• Test Instantiation Strategies - Provides flexible strategies to control whether test objects are persisted to a database, built in memory, or created as stubs.
• Testing Object Emulation - Creates complex Ruby objects and their associations for testing as a dynamic alternative to static fixture files.
• Test Sequence Generation - Produces incremental or cycling values for attributes to ensure data uniqueness across multiple test records.
• Sequential Value Generation - Maintains internal counters to provide incremental or cycling values for attributes to prevent data duplication.
• Dynamic Templates - Provides a simple syntax for creating dynamic blueprints that replace static fixtures with generated data.
• Lifecycle Callbacks - Implements build and creation callbacks to execute custom setup logic at specific stages of the object lifecycle.
• Alphanumeric Sequence Generation - Includes a sequence generator to produce incremental or cycling values, ensuring attribute uniqueness across test records.
• Bulk Test Record Generation - Produces arrays of objects in bulk using list methods while allowing attribute overrides for individual items.
• Composite Generation Strategies - Generates test objects using various strategies, including persisted instances and attribute hashes.
• Test Data Isolation - Provides unique and consistent data records for tests to ensure isolation and prevent data collisions.
